Welcome to the Community. QuickBooks Online is a flexible program that simplifies the way you manage your books. I'd glad to help.
I can see how adding jobs site to estimates and invoices would be beneficial for you. If you're using QuickBooks Online Plus or QuickBooks Online Advanced, you can use the location feature to track your jobs sites. I encourage you to review this article to set up and use location tracking in QuickBooks Online.
If you have any other questions, feel free to reach back out.
